我正在进行硒测试。对于某些用户，您没有相同数量的页面。这就是为什么我需要在我的代码中实现try catch，但遗憾的是每次他尝试并且元素不存在时他都会停止程序。当我把这个尝试捕获时给出NoSuchElementException。 我尝试在每次点击前放置，如果之前显示的元素，但显示相同的错误。
如果有人可以帮助我那将是非常好的！
try {
driver.manage().timeouts().pageLoadTimeout(10, TimeUnit.SECONDS);
driver.findElement(By.xpath("//input[@type='radio' and @value='true']")).click();
sleep();
driver.findElement(By.xpath("//input[@type='submit' and @value='>> valider <<']")).click();
sleep();
} catch (org.openqa.selenium.NoSuchElementException e) {
e.printStackTrace();
}

您需要首先检查元素是否存在，然后单击该元素，您可以创建以下方法：
public boolean isElementPresent(WebDriver driver, By elem) {
try {
driver.findElement(elem);
return true;
}catch(NoSuchElementException e) {
return false;
}
}
如果元素存在，此方法返回'true'。
然后，您可以在单击元素之前调用此方法以检查元素是否存在，如下所示：
try {
driver.manage().timeouts().pageLoadTimeout(10, TimeUnit.SECONDS);
if(isElementPresent(driver, By.xpath("//input[@type='radio' and @value='true']")){
driver.findElement(By.xpath("//input[@type='radio' and @value='true']")).click();
}
sleep();
driver.findElement(By.xpath("//input[@type='submit' and @value='>> valider <<']")).click();
sleep();
} catch (org.openqa.selenium.NoSuchElementException e) {
e.printStackTrace();
}

您正在catch块中打印e.printStackTrace();，并使用您的代码Stacktrace或某些代码
System.out.println("Element is not found");。
try {
driver.manage().timeouts().pageLoadTimeout(10, TimeUnit.SECONDS);
driver.findElement(By.xpath("//input[@type='radio' and @value='true']")).click();
sleep();
driver.findElement(By.xpath("//input[@type='submit' and @value='>> valider <<']")).click();
sleep();
} catch (org.openqa.selenium.NoSuchElementException e) {
System.out.println("Element is not found");
}
